Which CODEC for mjpg?
Locked
 
|
I am trying to put together a gst-launch pipeline to play some AVI
files. I'm using gst-launch -v uri=<my input filename> And the errors it returns: *** Message: don't know how to handle video/x-avi-unknown, fourcc=(fourcc)mjpg ERROR: from element /GstPlayBin:playbin0: You do not have a decoder installed to handle this file. You might need to install the necessary plugins. So, which plugin do I need to decode this file? I have browsed the plugins page, but can't find an mjpg capability. ------------------------------------------------------------------------------ Increase Visibility of Your 3D Game App & Earn a Chance To Win $500!

Install latest gst-ffmpeg package, there you will find ffdec_mjpeg.

JPEG is decoded by the 'jpegdec' element, in the jpeg plugin.
The problem you're describing sounds like the AVI demuxer doesn't recognise this file as containing jpeg, though. Perhaps another mapping entry needs adding to the riff lib.

I have also tried
gst-launch -v filesrc location=<my file> ! jpegdec ! ffmpegcolorspace ! ximagesink And it terminates without error after about a millisecond, but doesn't show any video. I can play this file in VLC.

You already said it was an AVI file, so I don't know why you're now
trying to decode it without an avi demuxer. As I said previously, the problem is clearly that the AVI demuxer isn't recognising this FOURCC, and fixing that would make it work.

Actually, I have tried a great many variations to try to get this to work.
So, if it is a problem in the AVI demuxer, I assume that this is not an issue I can resolve. Bummer. Perhaps I can get the source videos in some other format.

I have the opposite problem. I can make jpeg video files with:
gst-launch v4l2src ! video/x-raw-yuv ! queue ! ffmpegcolorspace ! jpegenc ! avimux ! filesink location=mjpeg.avi and the file plays back fine in gstreamer (using Totum on Ubuntu 10.04) but when I copy it over to a windows system it doesn't play. There are several MJPEG playback codecs on the Windows system. Gspot Codec Information on Windows shows a valid playback pipeline, but errors in rendering. I tried Theoraenc instead with: gst-launch v4l2src ! queue ! ffmpegcolorspace ! theoraenc ! oggmux ! filesink location=theora.ogv and again it plays fine in Totum but not on Windows (the Windows system can play back the ogg video sample files distributed with Ubuntu). |

Bingo! That was what was missing. Seems the OGV on Windows issue is my K-lite Codec pack is not up to date. VLC-win32 v1.1.5 plays it back fine. |
